SPHALERITE ( ZINC )
2016 TECH REPORT
Page - 22 - surface showings of,
12.8% zinc
1.15 % copper
Page - 26 - massive sphalerite
25 ft from shaft #1 has sphalerite showings from 10's of feet to 100's of feet.
What's Sphalerite ?
Zinc - historical reports peetaining to the mineral Sphalerite has found that copper can exist
with in a - Sphalerite.
Pagr 32 + 34 chalcopurite + sphalerite
Bth of these minerals are mentioned when it comes to - finding the best grades of gold.
Page 36 - i find very interesting
An unknown grey mineral was discovered along side of the gold
Hard not to think, copper. But... opoen to conjecture.
ROWAN DRILL INTERCEPT MAP
What's missing ?
The mineralization of host minerals to pair with each marker on each intercept .
If one were to know these values - what would the copper + zinc values be ?
Link only stays live for a few days - temp link - a map i downloaded from a RLG - pdf

Lots of coloration. Looks great.
One can see a dense core body with a good - 200m x 200m and of course if one scales to a 100m depth value the middle core body - extends with good mineralized wings
What are those colored markers - assigned to - as per - what minerals ?
Knowing this value per each drill intercept would allow a shareholder to know how to
assign the - sphalerite and copper values - found in the 2016 tech report.
Other minerals can increase the value of an existing gold ore body -
It could/might change the dynamics of this gold deposit to include potential ( other ) mineral credits that could/might change the mine model from - underground to open pit. What else does it do - it could take the presure off the junior of chasing high grade veins and instead of chasing more high grade veins - look at the current deposit in a different manner - asking that oh so important question - is this a deposit that is minable as it is - now. Taking into consideration of the other mineral credits.
Zinc with Chalcopyrite heated to 400 degrees = Sphalerite.
Hard to detect the copper.
What's the copper content of such a compostion ?
50% copper.
EXCERPT -
The mineral clearly contains major copper, zinc, and sulfur, but its small grain-size and poor polishing characteristics prevent wholly satisfactory quantitative analysis. Estimation, by comparison with the associated djurleite, and iron-free sphalerite, yields approximate copper, zinc, and sulfur contents of 50±3, 16.7±2, and 35±4 weight percent, respectively. No gross compositional variations were evident between several grains.
The analysis quote - is essentially pointing out that copper as much as, 50% is with in this matrix. That's something very significant and sometihng that can be overlooked.
What should RLG do ?
Should they do more drilling ?
Or.... resift their data - pull forward their 2016 tech report and take a closer examination of thier copper and sphalerite ( zinc ) values ?
As mentioned in last post....
it doesn't take much to amass a good zinc deposit that would complikment their current gold ounces. A small 100m x 100m x 100m depth of 1% zinc could afford additional mineral credit value not to mention - completely change the mine model from underground to a potential open pit... In my opinion - seeking out other mineral credits could greatly benefit RLG - if, other mineral credits are with sufficient grades.
I implore RLG to first read this small paper on, Copper + Sphalerite.
Invaluable information that speaks about the relationship of zinc and copper.
A paper on transitional metals - how sphalerite ( zinc ) and copper are closely related.
And.... how the " blue phase " can harbor a higher content of copper.
Can't help but think of thier - blue quartz.
SUPERGENE ALTERATION OF SPHALERITE AND ( OXIDATION )
Superb read.
https://www.minsocam.org/msa/collectors_corner/arc/cusphalerite.htm
Covellite = can display as a grey mineral.
blue phase locally contains as much as 15 (± 2) percent copper. In all cases, there is an abrupt compositional change at the contact with the zinc-free djurleite. Zinc and copper exhibit an inverse concentration relation, and comparison with the original sphalerite indicates that the blue phase maintains a metal: sulfur atomic ratio of approximately unity, and may probably be regarded as a cuprian sphalerite.
So, few more topics that might assist RLG.
NOW.. Is the ( 2000 yr ) contest still open - lol
Whereas, monies were offered to find another 6 million ounces ?
Would deciphering and ( potentially ) finding hidden minerals that are cloaked in transitional phases quailfy - basing new metals converted to Gold - EQ ounces ?
wink.
Yup.... i think RLG should do a double take on their copper and zinc values.
Reading the Tech report where it says.... 100's of feet of sphalerite only 35 ft away from
shaft #1 makes this topic all the more interresting.
Could advance this project al lthe quicker...
Cheers...
